API 5L X42 Welded Pipe Description
API 5L X42 pipe, also known as L290 pipe (according to ISO 3183), is named after the minimum yield strength of 42,100 Psi or 290 Mpa. It is a higher grade than B. API 5L has various grades up to X100, so x42 pipe is a low to medium grade and is required in large quantities in most oil and gas transmission pipelines.
GNEE offers API 5L X42/L290 welded ERW and HFW, LSAW. the product specifications are PSL1 and PSL2, with sizes ranging from the usual 4 inches, 6 inches, 8 inches, 10 inches, 12 inches, 16 inches, 20 inches all the way up to 60 inches.

API Welded Pipe Manufacturing
ERW: Resistance Welding up to 24 inches OD.
DSAW/SAW: Double Side Submerged Arc Welding, an alternative to ERW for larger diameter welded pipe.
LSAW: Longitudinal Submerged Arc Welding, also known as JCOE pipe, for outside diameters up to 56 in. JCOE is named for the J-, C-, and O-type fabrication process and uses a cold expansion process that releases pipe strength during deformation.
SSAW / HSAW: Spiral Submerged Arc Welded, or Spiral Submerged Arc Welded, up to 100 inches in diameter
